Peggy Olson

Lore & Background

Peggy Olson is initially presented as an innocent but determined young woman, eager to succeed at Sterling Cooper after graduating from Miss Deaver's secretarial school. Born on May 25, 1939, she was raised in Bay Ridge, Brooklyn, in a Roman Catholic Norwegian and Irish-American family. When she was 12, her father died of a heart attack in front of her. In the pilot episode, set in March 1960, she begins work as Don Draper's secretary.

She soon sleeps with account executive Pete Campbell, and months later they have another encounter on his office couch. After impressing executive Freddy Rumsen during a Belle Jolie lipstick focus group, she is asked to write copy and is soon promoted to Junior Copywriter. During her first year, she gains weight and experiences severe abdominal pain, which she attributes to a bad sandwich. At St. Mary's Hospital, she is shocked to learn she is in labor and gives birth to a healthy baby boy, but refuses to hold or look at him.

Season 2 begins 15 months later, with a slim Peggy and no mention of the birth. Flashbacks reveal she was in a mental hospital after a break with reality; Don encourages her to move forward, saying, "It will shock you how much this never happened." Her out-of-wedlock pregnancy causes tension with her Catholic mother and sister. In Season 3, she moves to Manhattan and becomes romantically involved with Duck Phillips.

When Don asks her to join his new agency, she initially refuses, noting everyone thinks he does her work. She eventually accepts and becomes part of Sterling Cooper Draper Pryce.

In Season 2, she becomes frustrated being left out of men-only business meetings; Joan advises her to "stop dressing like a little girl," leading Peggy to dress more professionally and get a dramatic haircut. In the Season 2 finale, during the Cuban Missile Crisis, Pete confesses his love, and Peggy reveals he got her pregnant and she gave the baby away. In Season 3, her ideas are frequently ignored, and when she attempts a raise, Don shuts her down.

She moves to Manhattan and considers leaving with Duck Phillips, but ultimately joins Don's new agency. In Season 4, she saves SCDP by signing Topaz Pantyhose after Lucky Strike leaves. In Season 5, she clashes with art director Stan Rizzo and is removed from the Heinz Baked Beans account after mimicking Don's authoritative style and offending the client. Key relationships shape her identity, particularly her complex mentorship with Don Draper, which evolves into mutual professional respect. Her bond with Joan Holloway offers solidarity between women navigating the same hostile environment.
